D3D10_DDI_BLEND_DESC structure (d3d10umddi.h)
The D3D10_DDI_BLEND_DESC structure describes a blend state.
Syntax

[in] BOOL AlphaToCoverageEnable;
BOOL BlendEnable[D3D10_DDI_SIMULTANEOUS_RENDER_TARGET_COUNT];
[in] D3D10_DDI_BLEND SrcBlend;

} D3D10_DDI_BLEND_DESC;
Members
[in] AlphaToCoverageEnable
A Boolean value that specifies whether transparency coverage is enabled. TRUE indicates transparency coverage is enabled; FALSE indicates transparency coverage is disabled. This member is relevant for multiple-sample antialiasing only.
[in] BlendEnable[D3D10_DDI_SIMULTANEOUS_RENDER_TARGET_COUNT]
An array of Boolean values that specify whether blending is enabled for each associated render target. TRUE indicates blending is enabled; FALSE indicates blending is disabled.
[in] SrcBlend
A D3D10_DDI_BLEND-typed value that indicates the blend mode of the source for all enabled render targets.
[in] DestBlend
A D3D10_DDI_BLEND-typed value that indicates the blend mode of the destination for all enabled render targets.
[in] BlendOp
A D3D10_DDI_BLEND_OP-typed value that indicates the blending operation for all enabled render targets.
[in] SrcBlendAlpha
A D3D10_DDI_BLEND-typed value that indicates the transparency blend mode of the source for all enabled render targets.
[in] DestBlendAlpha
A D3D10_DDI_BLEND-typed value that indicates the transparency blend mode of the destination for all enabled render targets.
[in] BlendOpAlpha
A D3D10_DDI_BLEND_OP-typed value that indicates the transparency blending operation for all enabled render targets.
[in] RenderTargetWriteMask[D3D10_DDI_SIMULTANEOUS_RENDER_TARGET_COUNT]
An array of 8-bit bitwise values that indicate the write properties for each associated render target. Each bit of each element must be set to one of the following values from the D3D10_DDI_COLOR_WRITE_ENABLE enumeration.
| Value | Meaning |
|---|---|
| D3D10_DDI_COLOR_WRITE_ENABLE_RED (1) | Writes red |
| D3D10_DDI_COLOR_WRITE_ENABLE_GREEN (2) | Writes green |
| D3D10_DDI_COLOR_WRITE_ENABLE_BLUE (4) | Writes blue |
| D3D10_DDI_COLOR_WRITE_ENABLE_ALPHA (8) | Writes a transparency level |
| D3D10_DDI_COLOR_WRITE_ENABLE_ALL (bitwise OR of 1,2,4,8) | Writes red, green, blue, and a transparency level |
Requirements
